Footwear sole



FIG. 1 is a perspective view of the footwear sole embodying the new design;

FIG. 2 is a bottom plan view thereof;

FIG. 3 is a right side elevational view thereof;

FIG. 4 is a left side elevational view thereof;

FIG. 5 is a front elevational view thereof; and,

FIG. 6 is a rear elevational view thereof.

FIGS. 1-6 show portions of an upper and a midsole in broken lines. The uppper and midsole are shown for environmental purposes and do not form any part of the claimed design.

The broken lines immediately adjacent to the solid lines throughout the views represent the boundary of the design. The broken boundary lines form no part of the claim. 

I claim the ornamental design for a footwear sole, as shown and described.
